However, there is a limit - and Pablo Martel, the manager of Club Atletico Union Santiago, has gone WAY past it.

Union Santiago play in the lower reaches of the Argentinian league, so the game you can see in the clip above was not exactly a high-profile affair. But just look at Martel's full-on explosion of rage.

He wanders out of his technical area as an opponent is running down the wing… and viciously boots him up in the air.

It's so brutal, even Alan Pardew - the Premier League's king of touchline rows - might consider it a bit much. It makes his infamous headbutt on Hull's David Meyler look like someone handing over a sternly worded letter of complaint.

In fact, the only similar manager-on-player attack we can remember happening on these shores took place during a charity game.
